In an exemplary embodiment, cutting tool has the first cutting surfaces and the second cutting surfaces being used alternatingly,
I.e. so that the first cutting surfaces be used for for the first time by with third time by and the second cutting surfaces be used for second by with
Pass through for 4th time, etc..Which greatly enhances the life-span of instrument.
In an exemplary embodiment, the first cutting surfaces and the second cutting surfaces have known curvature, for example, constant
Radius.In an exemplary embodiment, the first cutting surfaces and the second cutting surfaces have identical curvature (for example, identical
Constant radius).For example, this method can be related to the cutting tool with shaped form cutting surfaces (for example, with constant radius)
Use, wherein Part I/arc of cutting surfaces be used for for the first time by and cutting surfaces Part II/arc (for example,
It is relative with Part I) it is used to pass through for the second time.
In an exemplary embodiment, cutting tool includes at least part globulate (for example, substantially hemispherical or bigger)
Cutting head, wherein the cutting surfaces have constant diameter.
In an exemplary embodiment, the first time is by being to make work with second of each instrument that all refers in
The motion (the sometimes referred to as process of " moving to start to cut ") that the cutting surfaces of tool engage with blank, make the cutting surfaces of instrument

Detailed description of the invention
In order to illustrate the purpose of the improved method of workpieces processing especially rotating operation, there is provided Fig. 1 to Figure 11.
In general, workpiece 10 rotates and cutting tool 12 is moved and is in contact with rotational workpieces 10, so as to from described
The cutting blank of workpiece 10, for example, to form recess, groove or other forming sections in the workpiece 10.
Following article is detailed further, and this method is related to cutting circulation, i.e. instrument 12 is in the first direction relative to workpiece
The 10 motions first time " passing through " of cutting tool (be referred to as), so that the cutting head 20 of cutting tool 12 cuts the from workpiece 10
A part of blank.Instrument 12 then moves (second " passing through " being referred to as cutting tool) relative to workpiece 10 in a second direction,
So as to cut Part II blank from workpiece.Circulation is repeated as desired for, to cause such as gradually leading to by cutting tool 12
Cross and progressively remove blank from workpiece 10.
In an exemplary embodiment, method is used for roughening operation (that is, relative with finishing operation), for from workpiece 10
Desired site (for example, initial surface on workpiece 10) remove considerable fraction of blank 14, as shown in Figure 11.
This method is automation, and wherein electronic control system is programmed to control the cutting tool 12 during circulation is cut
Relative to the motion of workpiece 10, so as to which predetermined characteristic or forming section is made in the predetermined locations in workpiece 10.
Fig. 1 to Fig. 5 illustrates the embodiment that instrument 12 passes through relative to the first time of workpiece 10.
In Fig. 1, instrument 12 is static and warm-up is to engage blank (referring to Fig. 2).In this embodiment, this first
Move the axial direction () generally along the rotation axis relative to workpiece as shown in Fig. 1 to Fig. 5 upwards.In the He of instrument 12
During the initial engagement of workpiece 10, instrument 12 is controlled in the sometimes referred to as process of " rolling to start to cut " in cutting head
20 follow curved path when cutting in blank (referring to Fig. 3).Then, instrument 12 laterally moves, to cause in instrument 12
(referring to Fig. 5) before drawing back from blank and (sometimes referred to as " move and terminate cutting "), part of the cutting head 20 along blank is carried out
Cut (referring to Fig. 4), sometimes referred to as the process of " motion in cutting ".
Fig. 6 to Figure 10 examples go out instrument 12 relative to workpiece 10 second by or " reverse " pass through.Initially, first
It is secondary at the end of from workpiece 10 draw back after instrument 12 it is static (referring to Fig. 6), then with for the first time in the same way
But start cutting (referring to Fig. 7) along being moved with first time by opposite direction.Therefore, instrument 12 is rolled to start to cut
(Fig. 8), (Fig. 9) is then laterally moved to carry out another cutting along the part of blank before instrument is drawn back from workpiece
(referring to Figure 10).
As can be seen that for the second time by being carried out along with the direction in opposite direction or substantially opposite that first time passes through
's.Each alternating by direction of instrument 12 significantly decreases the possibility of volume generation (commonly referred to as " winding ").Therefore,
During with compared with the rotating technique of routine, the surface of the workpiece 10 rotated caused by chip contact is considerably reduced
The risk of abrasion.
Can be seen that motion of the instrument 12 in cutting from Fig. 3 and Fig. 4 or Fig. 8 and Fig. 9 comparison is linear (example
Such as, cutting head 20 follows straight path).In an exemplary embodiment, motion of the instrument 12 in cutting is in high feedback
Send speed, such as the 100% of optimum feed speed.
Instrument it is each by eliminating predetermined depth of cut from blank.In the embodiment shown in the drawing, pass through every time
Realize identical depth of cut.In other embodiments, for the second time by that can be controlled to cut to for the first time leading to
Cross different depth (for example, bigger depth) (etc.).However, in each embodiment, it is expected to follow using repeatedly cutting
Feature is made in ring, wherein every time by removing the thin sector of material from blank, so that feature is progressively formed (for example, as schemed
Shown in 11).This reduce implement load.
In the embodiment shown in the drawing, cutting head 20 has the first cutting surfaces 16 and the second cutting surfaces 18, and it replaces
Ground use, i.e. make the first cutting surfaces 16 be used for for the first time by with third time by and be used for the second cutting surfaces 18
Second by with the 4th offer, etc..The life-span of instrument is greatly improved in this.
In the embodiment shown in the drawing, the cutting head 20 of cutting tool 12 is fillet, and shows identical constant half
First cutting surfaces 16 and the second cutting surfaces 18 in footpath.Especially, there is cutting tool 12 the curved of constant radius to cut
Cut surface 16,18, wherein Part I/arc of cutting surfaces 16,18 is used for for the first time by and Part II/arc (example
Such as, it is relative with Part I) it is used to pass through for the second time.In this embodiment, instrument 12 has approximately hemispheric cutting head
20。
From Fig. 1 to Fig. 5 and Fig. 6 to Figure 10 comparison can be seen that for cutting circulation first time pass through instrument 12
Motion and (for example, in side of presumptive area 14) starts to cut at the first position of workpiece 10, and for cutting circulate
Subsequently through instrument 12 moves and starts to cut in the second place of workpiece 10, and the second place is away from first position
(for example, in opposite side of presumptive area 14).
Advantageously, instrument 12 move and first time by when position among the first position and the second place
(for example, the position in 25% to 75% region of distance between the first position and the second position, such as first position
Midpoint between the second place) terminate cutting.The drawing back between two " starting to cut " positions of instrument 12 allows to
Make motion and terminate to cut with fast feed rate (for example, 100% of normal feed rate), without worrying in each pass
Along the border of the presumptive area 14 in the direction of movement of tool.So, for preferred embodiment, for the first time by will not be lucky
Cut and pass through presumptive area 14.But before the opposite side that instrument 12 reaches presumptive area 14, instrument 12 is in its first time
By when retract just.
The motion that instrument 12 terminates cutting can be at moving than instrument 12 with feed rate (example high during starting cutting
Such as, optimum feed speed 100%).Which reduce total processing time.
Advantageously, control system can be programmed so as to be formed with workpiece by instrument for first time and engage and be controlled
System with its motion and start cutting when follow restriction curved path (such as, it then follows known radius).Therefore, instrument
Cutting surfaces 16 are programmed to follow controlled path, until cutting surfaces 16 reach the expectation depth of cut in presumptive area 14
(that is, being ready for linear incision operation).Then, cutting tool 12 is controlled to follow the (" cutting of straight/linear path
In "), the cutting surfaces 16 of wherein instrument engage with blank and along the predetermined cuts Depth Motions.
Advantageously, (that is, until instrument reaches when control system can be programmed to be used to roll in instrument 12 to start cutting
